" IMPROVEMENT IN HAY-ELEVATORS. i

The Schedule referred to in these Letters Patent and making part ci' the same.

To all whom t may concern: v l

lBc it known that I, F. R. DUFOUR, of Vevay, in

Vthe county of'Swit-zcrland, and State of' Indiana, have invented certainnew and useful Improvement-s in Hay-Elevators; and I do'hereby declare that the following is a full, clear, and exact description thereof, reference being V.hadto the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

`lhe nature of myinvention consists in the construction and general arrangement of a hayelevator,77 as will be hereinafter fully set forth.

,1n ord'cr to enable others skilled in the art to which my invention appertains, to make and use the same, I will now proceed to describe its construction and operation, referriinf` to the annexed drawings, which rep-` resent the frame-work of a barnwith the elevator attached. l

A represents 'the flame-work of a barn.

1n the centreof the ground i'loor of the barn A the horsepower is placed.

B is the sweep, to which the horse is hitched.

To the side of the sweep B is pivotcd a lever, C, the inner end of which is bent downward, forming a hook, a, that is just above and within the outer circumference of the reel D. This reel is provided, on its upper side, near its circumference, with a series of holes, for the hook a to catch into.

`When the horse is in motion, it is only necessary to raise thc outercnd of thc lever (Land the hook a will catch in one of said holes and turn thereel D. Then, to throw oii' the power, lower the outer end of the The hoisting-rope b, which is attached to the reel D, by means of a hook, c, passes around pulleys d, e, and f, in the floor of the barn, and up to a pulley, g, in the upper inner end of an upright pivoted crank, E, in the hay-mow, thence lover a pulley, h, in the outer end of said crank, down to the ground outside of t-he barn. A

Then the hay ishoisted high enough, the crank E swung around, so as to bring the hay within the mow, when the horse-power is thrown off', as above described, the hay unloaded from the fork, the crank 'swung outward Iagain, and the fork lowered to the ground.

Having thus fully described my invention,

That I claim as new, and desire to secure by Lettcrs Patents, is-

The arrangement, in combination with the horsepower B C l), of the hoisting-rope l), hook c, pulleys (l cj, and crank E, having pulleys g and h, substantiallyas shown and described.

1n testimony that I claimthe foregoing as my own, I atiix my signature, in presence of two witnesses.

F. R. DUFOUR.
